docs: def refreshUserMembership(self, users):
          """
          This operation iterates over every enterprise group configured in
          the portal and determines if the input user accounts belong to any
          of the configured enterprise groups. If there is any change in
          membership, the database and the indexes are updated for each user
          account. While portal automatically refreshes the memberships
          during a user login and during a periodic refresh (configured
          through the Update Identity Store operation), this operation allows
          an administrator to force a refresh.
